Description

Method for enhancing positioning measurement function and related communication device

The present invention relates to a method and related communication device for a wireless communication system, and more particularly to a method and related communication device for enhancing a positioning measurement function in a wireless communication system.

Long-term evolution (LTE), originally launched in the third generation partnership project (3GPP), is now considered a new wireless interface and wireless network architecture, providing a high-speed data Transmission rate, low latency, packet optimization, and increased system capacity and coverage. In the long term evolution technology system, an evolved universal terrestrial radio access network (E-UTRAN) includes a plurality of evolved Node-Bs (eNBs) and a connection complex number Mobile stations, the plurality of mobile base stations are also classified as user equipments (UEs).

Moving towards advanced high-speed wireless communication systems, such as for higher peak data rate transmission data, the Advanced Long Term Evolution (LTE-Advanced) (LTE-A) system is seen by 3GPP as an improved standardization of an LTE system. The main objectives of the LTE-A system are to achieve faster power conversion, improve the quality of cell edge transmission, and include multiple-input multiple-point transmission/reception (COMP) and multi-input multiple-output ( Multiple input multiple output, MIMO) and the like.

Coordinated Multicast Reception is seen as a tool by the Advanced Evolved Technology System to increase the coverage of high-speed data transmission rates, cell edge throughput, and system performance, as well as dynamic coordination between multiple geographically separated locations. When a client is located in a cell edge region, the client can receive signals transmitted by the cells, and the cells can receive the transmission data of the client.

For special reasons such as urgency considerations, there are several positioning methods for user-side location estimation. The positioning method supports an evolved universal terrestrial global wireless access network, including a cell identification and positioning method, an observed time difference of arrival (OTDOA) positioning method, and a network-assisted global navigation satellite system (network-assisted global navigation) Satellite System, GNSS) positioning methods and more. Please note that the observation of the arrival time difference positioning method may utilize the network configurable idle periods (OTDOA-IPDL) in order to enhance the hearing of the neighboring eNBs. Come help. The method of observing the arrival time difference positioning method includes a measurement of the UE and then the measurement result is sent to the network (for example, an evolved universal terrestrial global radio access network) for user location estimation. In general, the measurement is based on the difference in arrival time measured from different cells on the user side.

In the advanced long-term evolution technology system, the network side includes features for coordinating multi-point transmission reception and providing assistance data to the user for positioning measurement. The assistance data includes physical cell identities (PCIs) of candidate cells and associated transmission times of each candidate cell relative to a serving cell at the user end. Furthermore, since the distance between the user terminal and the candidate cell is different, the propagation delay between the user terminal and the candidate cell will also be different. Thus, the relevant transmission time is the arrival time of the reference signal (RS) required by the UE. Please note that the reference signal is transmitted to a positioning sub-frame, which is set as a candidate cell by the network, wherein the positioning sub-frame can be a normal sub-frame without data or a multimedia broadcast multicast without data. A sub-frame of the Multimedia Broadcast multicast service Single Frequency Network (MBSFN).

Therefore, according to the entity cell identification provided in the assisting data, the user terminal knows which cell participates in the localization measurement, and thereby measures the reference signal of the candidate cell, thereby generating a measurement result to the network. In this way, the network can perform user location estimation based on the measurement result.

However, due to the large number of relays and small-scale home base stations, the number of solid cell identifications for cell identification is insufficient to cope with the number of cells in advanced long-term evolution systems. In other words, there may be more than one cell sharing the same physical cell recognition, thus causing confusion in the identification of solid cells. For example, the UE measures one of the reference signals of a cell, and then transmits the measurement result to the network. Among them, the cell name is listed in the assisting data and has the same physical cell recognition as other cells. In this case, the network side is confused by the physical cell identification reported by the measurement result, and it is impossible to know which cell the solid cell recognition actually represents. That is to say, among these cells with the same physical cell recognition, the network does not know which one is actually measured by the user. Therefore, the network side is likely to estimate the location of the client using the wrong associated transmission time and the wrong cell location with the same physical cell identification.

In addition, since the advanced long-term evolution technology system specification is not clear, it is possible The following situations have occurred.

In the first case, when the client measures the reference signal from one of the cells and the physical cell identification of the cell is not provided in the assistance profile, the Advanced Long Term Evolution system does not regulate how the client should handle this situation. The measurement cell may not be set by the network to locate the measurement. Since the assistance data does not provide information about the cell, the relevant transmission time corresponding to this cell will not be provided by the assistance data. Therefore, the UE cannot know which associated transmission time should be used as an estimate of the arrival time of the reference signal.

In the second case, reference signal interference may occur among candidate cells for localization measurements. The UE can use a detection signal as a reference signal from a candidate cell, but the detected signal may actually be an interference signal. However, the advanced long-term evolution system does not clearly define how the client determines whether the detected signal is used for positioning measurement or just interference, thus affecting the positioning calculation of the user. In this case, the UE may make an erroneous judgment and interpretation of the signal reception that is actually a reference signal, thereby misleading the location estimation of the network.

In the third case, according to the characteristics of the advanced long-term evolution technology system, the cells used by the advanced long-term evolution system for positioning measurement should be coordinated and synchronized with each other. In other words, the network may know the time calibration information of the cell. However, the client can measure a particular cell that has not yet synchronized with other synchronized cells. Take a small-scale exclusive base station as an example. A small-scale dedicated base station can control several small coverage areas of closed subscriber group (CSG) cells, such as high-bandwidth wireless network access in home and office, as well as high efficiency and effective price for indoor coverage. Cost-effective capacity solution. A small-scale dedicated base station can provide exclusive permissions to specific clients. The closed user group is fine The cells do not interfere with any of the normal cells in the advanced long-term evolution technology system and are not synchronized with these cells. Therefore, the network side does not have the time calibration information of the closed user cells, so that there is not enough information to locate the measurement of the user terminal that can access the closed user cells, thereby causing the user positioning calculation error.

Please refer to FIG. 2, which is a schematic diagram of a communication device 20 according to an embodiment of the present invention. The communication device 20 can be the mobile device or the network terminal in FIG. 1 , and includes a processing device 200 , a storage unit 210 , and a communication interface unit 220 .

The code 214 includes a plurality of communication protocol level codes, and the communication protocol level code is a Radio Resource Control (RRC) layer 300 and a Packet Data Convergence Protocol (Top).

On the other hand, when the communication device 20 is regarded as the network end in FIG. 1, the RRC layer 300 of the network side is based on a control signaling (for example, a configuration signaling or a dedicated signaling). Or system information that provides a measurement configuration (eg, assistance data) to the mobile device.

Please refer to FIG. 4, which is a flowchart of a process 40 according to an embodiment of the present invention. The process 40 is used by a network of a wireless communication system to enhance positioning measurements. The process 40 can be compiled into the code 214 and includes the following steps:

Step 400: Start.

Step 410: The plurality of identification data including the plurality of cells are used in an assisting data, wherein the plurality of cells are used for positioning measurement of a user end of the wireless communication system, and are identified according to the plurality of identification data.

Step 420: End.

According to the process 40, the assistance data includes a plurality of identification data corresponding to a plurality of cells, and the plurality of identification data can be used to identify a plurality of cells. Each identification data includes physical cell identity (PCI), cell global identity (CGI), and cellular information (eg, closed user group related information, closed user group identification, or closed user). The group indicates) at least one of related information, CSG identification, or CSG indicator) for identifying each cell. It is worth noting that the plurality of identification data in the assistance data can be unique in the wireless communication system and not used by other cells. Therefore, the plurality of cells can be uniquely identified through the plurality of identification data. Thus, one of the mobile devices of the mobile device of FIG. 1 can identify each cell having the same physical cell identification based on the identification data to avoid confusion caused by cells having the same physical cell recognition.

Please note that the plurality of cells may comprise a closed subscriber group (CSG) cell controlled by a small range of home base stations, and several of the cells may have the same physical cell recognition. . In such a case, the client can use other information in the assistance material (eg, global cell identification, closed user group identification, or closed user group indication) to identify the cell, thereby avoiding having the same entity. Confusion of cells recognized by cells.

In addition, the network may further include positioning signal related information corresponding to the plurality of cells in the assistance data. The positioning signal transmission time related information includes a positioning signal transmission time difference between each cell and a serving cell of the user terminal. Since the positioning signal transmission time of the plurality of cells may be different, according to the positioning signal transmission time related information, the UE may identify a plurality of cells with or without the same entity cell identification.

For example, according to the process 40. When the positioning measurement of the UE is triggered by the network, the network determines the plurality of cells used by the UE to perform the positioning measurement, and then provides assistance data, which includes physical cell recognition of multiple cells, global cell identification, and At least one of the three types of cell information that can uniquely identify each cell, and the positioning signal related information of the plurality of cells to a user. Please note that when the network detects that some of the cells of the plurality of cells have the same physical cell discrimination, the network can provide the assistance data, which includes solid cell recognition, global cell identification, and use of a plurality of cells. It is unique to identify at least one of the cellular information of each cell, and the information about the positioning signal transmission time of the plurality of cells. Thereafter, the user measures the cells, and the solid cells are discriminated from the assistance data, and the measurement results including the measured cells are generated and reported to the network. Therefore, the network can use the measurement report to be used as a location estimation of the UE.

In addition, the network may include a positioning subframe configured in the system information of the cell. The positioning sub-frame is configured for reference signal transmission of cells. Since the positioning sub-frame is configured in the system information of the cell, the user terminal can identify a plurality of cells according to the positioning sub-frame configuration. In other words, when the physical cell discrimination of the cell measured by the user terminal may or may not be provided in the assistance data, the user terminal distinguishes a plurality of cells with or without the same entity cell discrimination according to the positioning subframe configuration. .

According to the process 40, the user can perform corresponding actions. Please refer to FIG. 5, which is a flowchart of a process 50 according to an embodiment of the present invention. The process 50 is utilized in a client of a wireless communication system to enhance positioning measurements. The process 50 can be compiled into the code 214 and includes the following steps:

Step 500: Start.

Step 510: Receive an assistance data from a network end of the wireless communication system, where the assistance data includes a plurality of identification data for a plurality of cells of a positioning measurement of the user terminal.

Step 520: Identify a plurality of cells according to the plurality of identification data.

Step 530: End.

According to the process 50, the user terminal identifies the plurality of cells according to the plurality of identification data of the plurality of cells, wherein the identification data is included in the assistance data provided by the network. Each identification data includes at least one of solid cell discrimination, global cell discrimination, and cellular information for identifying each cell.

In addition, the assistance data may further include information related to the positioning signal transmission time of the plurality of cells, and the mobile device transmits the time-related information according to the positioning signal to identify the plurality of cells. In addition, the UE can read system information from the plurality of cells, wherein the system information includes a positioning subframe configuration transmitted from the reference signals of the plurality of cells. Therefore, the UE can identify the plurality of cells according to the positioning subframe configuration. For a detailed description, please refer to the above, and I will not repeat them here.

The process 50 is taken as an example. The user performs the positioning measurement according to the assistance data provided by the network, and then generates the measurement report. Finally, the UE transmits the measurement report to the network, and the measurement report is used by the UE to report the measured cells. Before transmitting the measurement report to the network, the user uses the confirmed assistance data (identification data and the information related to the transmission time of the positioning signal) and the broadcasted system information of the positioning subframe configured on the measured cell. Medium, identifying a plurality of cells that have been measured. Alternatively, before identifying the measured cells (for example, confirming physical cell discrimination, global cell discrimination, positioning sub-frame configuration, at least one of them, and positioning signal transmission time related information), the client may transmit first. The measurement report is sent to the network. In this case, when the UE detects that one of the return cells has the same physical cell identification in the measurement report, or when the user detects that the measured cell is not reported by the measured cell, the user The terminal can notify the network that the previous measurement report is incorrect.

Please refer to FIG. 6. FIG. 6 is a flowchart of a process 60 according to an embodiment of the present invention. The process 60 is utilized in a client of a wireless communication system to enhance positioning measurements. The process 60 can be compiled into the code 214 and includes the following steps:

Step 600: Start.

Step 610: Perform a localization measurement corresponding to the plurality of cells.

Step 620: Generate a positioning measurement report for reporting some cells of the plurality of cells that have been measured by the user terminal to a network end.

Step 630: The plurality of identification data of the cells that have been measured by the user end are included in the positioning measurement report, whereby the measurement cells are identified according to the plurality of identification data.

Step 640: End.

According to the process 60, the user end includes the identification data of the measured cells in the measurement report. Each identification data includes at least one of solid cell identification, global cell discrimination, and special cell information (eg, closed user group related information, closed user group identification, or closed user group indication) for identification. Every cell. Therefore, the network can identify each return cell according to the identification data, and accordingly, the network knows which cell has actually been measured, so as to use the correct information corresponding to the returned cell, and use it to estimate the position of the seat user. use. In addition, in addition to the identification data of the measured cells, the user terminal further includes information on the positioning requirements of the measured cells (for example, reference signal (RS) arrival time) in the measurement report.

According to the process 60, for example. The client performs a positioning measurement corresponding to the plurality of cells, the plurality of cells may have the same physical cell discrimination, and may be used by the network to determine the positioning measurement for the client or any detected by the client. cell. Then, the UE generates a measurement report to the network. Before transmitting the measurement report to the network, when a first cell and a second cell have been measured, the user terminal can determine whether a first solid cell of the first cell of the plurality of cells is discerned and A second solid cell discrimination of the second cell of the plurality of cells is the same. Alternatively, when the first entity cell discrimination and the second entity cell discrimination are the same, the user end may include a measurement result corresponding to the first entity cell discrimination and an amount corresponding to the second entity cell discrimination. At least one of the results of the measurement is in the measurement report, and the measurement report includes an indication for indicating which cell the first entity cell discriminates and the second entity cell discrimination respectively correspond to.

Please note that the location measurement may be triggered by the client based on the capabilities of the client. For example, before the network configuration information (for example, positioning sub-frame configuration or assistance data) is used to locate the measurement by the user, the user end may have sufficient demand information to locate the measurement. Therefore, the user automatically triggers the positioning measurement. In addition, for a specific situation, such as an emergency, when the UE is in a radio resource control idle state, the network may request the UE to perform positioning measurement through a paging message or a system information update. On the other hand, when the UE is in a RRC connection state, the network may request the UE to transmit the paging message, a signaling specific to the mobile device, or a layer above the radio resource control layer of the network. A signaling sent (eg, mobile terminal paging or service steering) is used to perform positioning measurements.

Please refer to FIG. 7. FIG. 7 is a flowchart of a process 70 according to an embodiment of the present invention. The process 70 is utilized in a client of a wireless communication system to enhance positioning measurements. The process 70 can be compiled into the code 214 and includes the following steps:

Step 700: Start.

Step 710: Determine a plurality of cells for positioning measurement of a user end of the wireless communication system.

Step 720: When the first entity cell identification of a first cell of the plurality of cells is the same as the identification of a second entity cell of a second cell of the plurality of cells, the first entity cell identification is not included. And the second entity cell is not included in the assistance data.

Step 730: End.

According to the process 70, when the physical cell identification data of at least two cells used for the localization measurement is the same, the network side does not provide any assistance data. In other words, the network side is not included in the physical cell identification data used by the at least two cells that assist the data to locate the measurement, thereby avoiding confusion of the physical cell identification data.

For example, according to the process 70. The network first determines which cells are used for location measurements. If the network detects a first cell and the physical cell identification data of the first cell has the same content as the physical cell identification data of a second cell, the network should not include the first cell in the assisting data. The physical cell identification data and the physical cell identification data of the second cell. Therefore, the user does not measure the cell with the same physical cell identification data as other cells and uses it to locate the measurement. According to the user's positioning measurement report, the user does not report any cell identification data. On the other hand, if the user end finds that at least two cells have the same entity cell identification data, the client does not ignore the location measurement or only returns at least one cell with an indication to indicate which cell. The instructions include information that assists the network in identifying which cells are being rewarded (eg, cell global discrimination).

Please refer to FIG. 8. FIG. 8 is a flowchart of a process 80 according to an embodiment of the present invention. The process 80 is utilized in a client of a wireless communication system to enhance positioning measurements. The process 80 can be compiled into the code 214 and includes the following steps:

Step 800: Start.

Step 810: Receive, from a network end of the wireless communication system, an assistance profile including a plurality of physical cell identifications for a plurality of cells for a positioning measurement and an associated transmission time.

Step 820: When the positioning measurement is initial, detecting an arrival order of the plurality of reference signals transmitted by the plurality of cells:

Step 830: When the arrival order conforms to the related transmission time or an order indicated in the assistance data, the positioning measurement result corresponding to the plurality of cells is returned.

Step 840: End.

According to the process 80, the client receives assistance data including physical cell recognition for location measurement, where more than two cells may have the same physical cell recognition. If the arrival order of the reference signals detected by the user terminal from those cells having the same physical cell identification has a specific relationship with the relevant transmission time in the assistance data, the user end reports the measurement results of the cells having the same physical cell identification. Please note that this specific relationship means that the reference signal arrival order corresponds to the relevant transmission time of the assistance data.

For example, according to the process 80. It is assumed that the user terminal measures Cell1~Cell3 with the same entity cell identification according to the assistance data, and the relevant transmission time T1~T3 of the cell Cell1~Cell3 is different in the assisting data. According to the relevant transmission time of the cells Cell1~Cell3, the UE can estimate the arrival order of the reference signals from the cells Cell1~Cell3. It is assumed that the arrival order of the reference signals of the cells Cell1~Cell3 is Cell1, Cell2, and finally Cell3. When the UE first receives a reference signal from the Cell1, the UE returns a measurement result of the Cell1 to the network. When the UE receives a reference signal from the Cell 2 and the measurement result of the Cell 2 has been reported, the UE returns a measurement result of the Cell 2 to the network. Moreover, when the UE finally receives a reference signal from the Cell3 and the measurement results of the Cell1 and the Cell2 have been reported, the UE returns a measurement result of the Cell3 to the network. Please note that the measurement result of Cell2 is reported to the network only when the measurement result of Cell1 has been reported. Otherwise, the measurement result of Cell2 will not be reported to the network. Similarly, the measurement result of the Cell3 is reported to the network only when the measurement results of the Cell1 and the Cell2 have been reported. Since the measurement results of the Cell1~Cell3 are sequentially reported, the network can distinguish the Cell1~Cell3 having the same entity cell identification according to the order, and accordingly use the correct information (for example: related transmission time) for the location estimation of the user end. .

Please refer to FIG. 9. FIG. 9 is a flowchart of a process 90 according to an embodiment of the present invention. The process 90 is utilized in a network of a wireless communication system to enhance positioning measurements. The process 90 can be compiled into the code 214 and includes the following steps:

Step 900: Start.

Step 910: Detect or configure a first entity cell identification of a first cell and a second entity cell identification of a second cell.

Step 920: When the first entity cell identification and the second entity cell identification are the same, configuring a first transmission form for positioning measurement transmission to the first cell and a second transmission for positioning measurement transmission Forming the second cell.

Step 930: End.

According to the process 90, when the network detects that at least two cells have the same physical cell identification, the network side configures different positioning forms (for example, different positioning reference signal forms or time division multiplexing (TDM)/ Frequency-division multiplexing (FDM). This form of location can be included in the system information or provided in the assistance material. Therefore, the user can identify cells having the same physical cell recognition in the localized form according to the system data or the assistance data of the read cells.

Please refer to FIG. 10, which is a flowchart of a process 1000 according to an embodiment of the present invention. The process 1000 is utilized in a client of a wireless communication system to enhance positioning measurements. The process 1000 can be compiled into the code 214 and includes the following steps:

Step 1010: Start.

Step 1020: Receive an assistance profile containing solid cell identification for a cell for localization measurement.

Step 1030: Detect a reference signal corresponding to a first cell, wherein the physical cell identification of the first cell is not included in the assistance data.

Step 1040: A positioning measurement result including the first cell is in the positioning measurement report.

Step 1050: End.

According to the process 1000, when the user detects the reference signal from the cell, in the measurement report, the user end includes the measurement result of the cell, wherein the entity identification data of the cell is not included in the assistance data. In other words, even when the measured cells are not provided by the network, the client reports a measurement result of one cell to the network.

In addition, the client may include physical cell identification and discriminating data of the measured cells (eg, global cell identification) in the measurement report. For a detailed description, please refer to the above, and I will not repeat them here.

According to the process 1000, for example. The client knows which cells are involved in the location measurement based on the assistance data provided by the network. When the user detects a reference signal from a cell whose physical cell identification is not included in the assistance data, ie, the cell does not participate in the localization measurement, the user terminal still contains the measurement report of the cell. Since the solid cell recognition of the cell is not included in the assisting data, a related transmission time of the cell may not be included in the assisting data. In this case, the relevant transmission time of the cell can be reported as a relevant transmission preset value or compensated according to the relevant transmission rule. The preset value or rule for the relevant transmission time of the cell is determined by the specifications of the network or for the user. Therefore, the network uses the preset value or rule and the relevant transmission time of the physical cell of the other cells included in the assisting data (ie, the relevant transmission time learned by the network), so as to regain the positioning for the user. Estimated correct positioning of the relevant transmission time.

In addition, when the detected reference signal is from a cell, the cell is located in a coordinated and synchronized (eg, time alignment) cell group in a multimedia broadcast multicast service single frequency network ( In the Multimedia Broadcast multicast service Single Frequency Network (MBSFN), the associated transmission time of the single-frequency network cell of the multimedia broadcast multicast service may be used by the network to use the preset value or defined in the multimedia broadcast multicast service single frequency network. The area (eg, the associated transmission time is zero between the multimedia broadcast multicast service single frequency network areas is zero). Therefore, the network can regain the correct correlation transmission time of the single-frequency network area of the multimedia broadcast multicast service used as the location estimation of the UE.

Please refer to FIG. 11 , which is a flowchart of a process 1100 according to an embodiment of the present invention. The process 1100 is utilized in a client of a wireless communication system to enhance positioning measurements. The process 1100 can be compiled into the code 214 and includes the following steps:

Step 1110: Start.

Step 1120: Determine whether the reference signal is used for positioning measurement according to a cell information of a cell, a cell form carried by a reference signal corresponding to the cell, or a signal strength of the reference signal.

Step 1130: End.

According to the process 1100, when the user detects the cell information (for example, physical cell identification or global cell identification), the user is carried in the detected reference signal or the signal strength of the detected reference signal has reached a certain threshold. The user considers that the detected reference signal is used for positioning measurement. On the other hand, if the cell information is not detected in the reference signal or the signal strength of the reference signal does not reach the specific threshold, the user may consider that the detected reference signal is a reference signal interference.

Please refer to FIG. 12, which is a flowchart of a process 1200 according to an embodiment of the present invention. The process 1200 is utilized in a client of a wireless communication system to enhance positioning measurements. The process 1200 can be compiled into the code 214 and includes the following steps:

Step 1210: Start.

Step 1220: Perform a positioning measurement to generate a positioning measurement report.

Step 1230: Obtain time calibration information about a plurality of cells of the localization measurement.

Step 1240: Include the time calibration information in the positioning measurement report.

Step 1250: End.

According to the process 1200, the UE includes time calibration information of the cell in the measurement report, so when receiving the measurement report from the UE, the network may have sufficient information for the estimation of the user positioning. Please note that the user can use the transmission synchronization signal to make a plurality of cells, and obtain time calibration information of a plurality of cells.

According to the process 1200, for example. The network side configures a plurality of cells for the user to perform the measurement report (for example, according to the assistance data). The user performs the localization measurement according to the configured cells, and measures some cells of the configured cells. During the positioning measurement, the user can detect whether the frame in the measurement cell is calibrated, partially calibrated or not, and obtain time calibration information of the measurement cell. In the measurement report, the user end contains the time calibration information of the measurement cell, so the network side can estimate the positioning of the user end more accurately. Please note that the calibration information may include at least one of a calibration indication, a calibration level, or a calibration interval.

The steps of all the foregoing steps include the suggested steps, which can be implemented by means of a device, which can be hardware and firmware (combined with hardware devices and computer instructions and data, and computer instructions and data belong to the read-only software on the hardware device). ), or electronic system. The hardware can be an analog microcomputer circuit, a digital microcomputer circuit, a hybrid microcomputer circuit, a microcomputer chip or a germanium chip. The electronic system can be a system on chip (SOC), a system in package (Sip), a computer on module (COM), or a communication device 20.

In summary, the implementation method and apparatus are provided to enhance the positioning measurement. In addition to the additional information on the cells containing the localization measurements, the client can distinguish cells with the same entity cell identification, thereby avoiding the confusion of solid cell recognition.
